'What do we really hear when we hear the wind? In fact, what we are hearing is moving air colliding with – and playing – the surface of the Earth. It is the grass that is singing and the trees that are soughing. When the wind blows, each thing creates its own distinctive sounds, from the swells of the sea to the sands of the desert, from the rolling mountains to the vast ice-sheets, from our blocky buildings to the cables that connect them overhead.'
